NONOS_SDK 1.5.4.1 Patch causing fatal errors

[winzin311]

Dear Espressif,

After applying the 1.5.4.1 patch files to my stable 1.5.4 code base, upon flashing my eagle.flash.bin and eagle.irom0text.bin, my ESP8266 module (ESP-12 or ESP-12F) goes berserk and the blue led keeps flashing continuously. Using putty, I see that some fatal exception kept occurring.

I have followed the instructions mentioned in patch notes by flashing blank.bin to 0x7e000, then esp_init_data_default.bin to 0x7c000. I replaced the lib.a's, added the sample code in user_main.c to my application's user_main.c and loaded my application (eagle.flash.bin -> 0x00000 and eagle.irom0text.bin -> 0x40000. My flash map is 0.

If I go back to program the application binaries from my 1.5.4 codebase, my applications starts as per normal.

Have you seen a similar issue?

Thank you.

I tried the patch with our AT example, everything ok.
could you share your source code for my verification?

Hi Rubin,

Sorry for the extremely late reply, thanks for your comment. Honestly haven't gone back to try this out. I think I'll try it on the new 2.1.0 version and see if I have the same issue.

Thanks!

Ok, just tried to replicate the same on 2.1.x and seems I don't see the issue I was having anymore!
